Manchester City boss Roberto Mancini has all but conceded the title to Manchester United after defeat to Arsenal.
Mancini admitted the defeat "probably" ended City's title hopes, with Manchester United having earlier opened up an eight-point gap.
He said: "United, in the last 12 games, have won 11 with one draw. They've done incredibly in the last two months.
"But, in football, it can change. Ten days ago, we were one point behind. Today, we are eight points. This can change also for them.
"Clearly, they have more experience than us, so probably it's difficult, but until it's impossible, we need to hope."
Mancini insisted he was "100 per cent" the right man to guide City to the title, pointing out the improvements he had made.
